The G.I.M.P. Festival is a 2-day weekend music festival usually taking place in the August of each year. The G.I.M.P., as well as being a humorous name, stands for Great International Music Personalities. The festival was first held in 2003, in Eastbourne's Princes Park. Amongst the acts performing were AC/DC and Muse.

The festival had to be cancelled - it was to be just a Bowling For Soup concert with support from Billy Talent, MC Lars and Zebrahead, but all 4 bands were stranded in the USA due to weather conditions.

NB: Although companies can buy the naming rights up to a year in advance, no company is allowed to have the rights 2 years in a row. Red Bull and Relentless, for example, have held the rights for 2 years each, but they have not been consecutive years.

Eastbourne has also started bidding for the concert to return to the town in 2021. The bid is being sponsored by O2 and Red Bull, and would see the arena in Eastbourne increased in size to 20,000 tickets. This, however, according to DHC Concerts, is not large enough for the fanbase that the Festival now has, and has said that the Festival would probably never return to Eastbourne. Eastbourne Borough Council responded to this, stating that the Festival would lose fans from not moving back into Eastbourne, and would lose the unique atmosphere.
